Need help ?
Something keeps draining my battery about once a week.
Usually happens over night period.
What to check first?
Can my remote starter alarm do this ? or a bad ecu ?
The lights and fan are the things i checked already.

 

bad battery?

 

I forgot to mention this is the second battery i have replaced.

 

1) may be your alternator is not charging too well thus the battery is never full to begin with
2) Again, the battery. Try a different brand. DieHard is very good in my opinion.

 

If the alternator is bad. I am thinking i would get dimming problems and
power loss stuff. I can change the battery again with another brand.
Any other suggestions to check ?
Thanks

 

Can't i check the alt. by testing voltage with the car on and with the car off.
The Voltage sure be : 13.5 + with the car running.

 

It looks like you have a short somewhere. If the alarm is not installed properly its possible the short is occurring there. If this is the second battery you have replaced in a very short time then I doubt replacing it with a new battery will solve anything.

Bad alternator. The diode pack is bad in it.

OR, check this first.

Check the OHMS between the CYLINDER head and the (-) TERMINAL of the battery. If it's more than 0.1 OHMS, you have a bad engine ground.

Outtie.

 

The reading from the alternator are:
13.7 with no load.
12.7 with fans on and headlights, AC and radio
0.3 amps current draw with car off.

Is this average?
